JOSEPH ZALOWITZ, OF NEW YORK, N. Y.

GEM SETTING.

Application filed. August 10, 1921.

To aZZ whom it may concern:

Be it known that I, Josnrrr ZALOWITZ, a citizen of the United States, resident of New York, in the county of New York and State of New York, have made a certain new and useful Invention in Gem Settings and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of this specification.

Figure l is a plan view of the invention.

Figure 2 is a. section on the line 22 Figure 1.

Figure 3 is a side view of the invention.

Figure a is a section on the line 4l-4- Figure 1. I

The invention has relation to gem settings, and particularly to cluster settings, having for an object to provide a more secure setting for the stones, particularly adapted for closed back settings, rendering the setting of the stones more simple, and giving a better coloring to the stones as set.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings illustrating the invention, the numeral 2 designates the body of the setting, provided with an outer circumferential series of teeth 3, converging towards the back of the setting, into points 4, extending backwardly of said body, and adapted for attachment to an annulus 5, by a suitable cement or solder, a pin 6, being in some cases secured to said annulus.

Each tooth 3 is indented centrally there-- of, at 7, thereby making each tooth of V- form in side or edge view, the adjacent branches of each pair of said teeth being united to form a projection 8 in the nature Each pair of said teeth therefore forms a W in side view, as in Figure 3 of the drawings and is separated from adjacent pairs of similarly formed teeth by spaces or indentations 9, which extend more deeply or inwardly of the setting than does the indentation 10 between the members of each pair of said teeth.

For each pair of teeth there is provided a conical or tapered recess or seat 11, for a stone, and the projection 8 of each pair of Specification of Letters Patent.

teeth is in line radially with the center of the related seat 11 and the center of the body of the setting. The annular series of recesses or, seats 11, meet each other tan gentially, triangular projections 12 being thereby formed and filling in the angles between said seats at the outer sides thereof, each said projection 12 being united with the adjacent branches of adjacent pairs of teeth and the indentation 9 extending centrally inward of the triangular projection 12 to make said projection of V form, the branches of which are adapted 'to be spread by a punch placed thereon to overhang the seat 11 and a stone 13 fitting in said seat, and thereby holding the stone in place, a punch placed upon the projection 8 spreading the same and causing it to also overhang the seat 11 and the stone for the same purpose. It will be noted in this connection that the single projection 8 and the V-form projections 12 both project above the seat 11 so as to be adapted to be spread to overhang said seat.

A central seat 14 of conical form is tangential to the annular series of seats 11, thereby providing projections 15 filling in the intervals between the seats and capable of being spread by a punch placed thereon to overhang said central seat and a stone 16 locat-ed therein to hold the stone in place, and also capable of being spread to hold the outer series of stones 13 in place, said proj ections 15 similarly all projecting above the seat 14:.

Each pair of teeth 3 formed as stated is made up of four inclined strut members 17 united centrally to form the projection 8, and united at the ends to the triangular projections 12, thereby providing means for bracing the projections 8 and 12 when being spread for the purpose stated and avoiding the distortion of the setting in the operation of securing the stones in place therein.

In spreading the projections 15 for the purpose stated, said projections will be braced against the action of the punch by the substantially pyramidal portions 18 of the body of the setting lying immediately under the said projections, and connected with each other annularly around the setting.

The annular series of seats 11 for the stones meet each other tangentially below the face of the body of the setting, this being true as to the meeting of the center seat 1.4 with the seats 11, whereby the projections 12 and 15 project vertically or parallel to the longitudinal central axis of said seats, being thereby adapted to be more readily spread or upset to overhang the stones and secure the same in position.

I claim 1. In a gem. setting for clusters, at body hav'ng tapered seats in an annular series and a central tapered seat, the peripheries of ,said seats meeting each other to form projections located between the seats and adapted to be upset to secure the stones in said seats in position, the outer of said projcctions being cut away to provide V-forin projections and point projections in line radially with the centers of said seats and the center of the setting. V

2. In a gem setting for clusters, a body having tapered seats, the perimeters of said seats meeting each other below the face of said body, projections thereby formed and adapted to be spread or upset over the edges of stones in said seats to secure the same in position and strut braces for said projections in the spreading or upsetting thereof.

3. In a gem setting for clusters, a body 7 having tapered seats theperimeters of which meet each other tangentially below the face of said body, V-form projections located be tween said seats, and point projections in line radially with the centers of said seats and the center of the setting, said projec tions being adapted to be spreader upset to secure the stones in position, and strut braces for said projections in the spreading thereof. 4. In a gem setting for clusters, a body having tapered seats the perimeters of which meet each other tangentially below the face of saidbody, V-form projections located between said seats, and point projections between said V-for1n projections, all of said projections being adapted to be spread to overhang stones in said seats, and strut braces backing up said projections and con verging towards the back of the setting.

5. In a gem setting for clusters, a body having tapered seats the perimeters of which meet each other below the face oi said body, V-form projections located between said seats, and adapted to be spread to overhang said seats, and braces backing up said projections and retreating backwardly.

In testimony whereof I afliX my signature in presence of two witnesses.
